Hi All , javascript function to change multi-modbus serial point value

---

hi all , i wanna to make an javascript function to loop into set of modbus settable points to change it's values , actually to toggle on/off each point depends on parameter that i should provide.
i found something here but it serve only one point value , lets say that my data points name are b1_r01,b1_r02,b1_r03,b1_r04 ... b1_r08 , i wanna to change it's values after pressing on a button in a page using dashboradV3.1.
and here the script i found:
<script>function togglePoint( dataPointXid ) {
var getPoint = new XMLHttpRequest();

getPoint.addEventListener('load', function() {
    //Consider returning if empty response text
	var point = JSON.parse( this.responseText );
	point.enabled = !point.enabled;
	
	var putPoint = new XMLHttpRequest();
	putPoint.open('PUT', '/rest/v1/data-points/'+point.xid, true);
	putPoint.setRequestHeader( 'X-XSRF-TOKEN', /XSRF-TOKEN=(.*?);/.exec(document.cookie)[1] );
	putPoint.setRequestHeader( 'Accept', 'application/json' );
	putPoint.setRequestHeader( 'Content-Type', 'application/json' );
	putPoint.send(JSON.stringify(point));
});

getPoint.open('GET', '/rest/v1/data-points/'+dataPointXid, true);
getPoint.setRequestHeader( 'X-XSRF-TOKEN', /XSRF-TOKEN=(.*?);/.exec(document.cookie)[1] );
getPoint.setRequestHeader( 'Accept', 'application/json' );
getPoint.send();

};

togglePoint("F6_B01_R01");
</script>

Hi Joe,

Sorry this took so long to respond to. Is that toggle function working for you? You could tie your button to call a function that calls the toggle function several times,

function toggleStuff() {
  togglePoint("F6_B01_R01");
  ...
  togglePoint("F6_B01_R08");
}

but perhaps your question is more complex? There are also endpoints for updating several data points at once, if you wished to make fewer API round trips, the /rest/v1/data-points endpoint (not data point xid, must be supplied in each point in the list in the PUT content.
